From your perspective the war started in 2022.
In reality that phase of the war started before. Russia did not improvise this war. They started disrupting the supply in 2021 to ensure that Europe would not fill their strategic reserves / winter storage during the summer, thus insuring maximum leverage when they needed it. This is well documented [1]
Note that this is just talking about this phase of the war. Hostilities started in 2014 when parts of Ukraine "suddenly self-liberated" themselves. Helped by mysterious soldiers in professional but unmarked uniforms.

Nobody has sabotaged European energy security more than European governments. The divestment from nuclear and reliance on LNG was an obvious disaster in the making. Taiwan has made a similar blunder and will pay the price at the next whiff of geopolitical instability.
You've just read how Russia literally sabotaged European energy security and you compared this to... some European countries taking a suboptimal decision?
And Europe is not a single country. My country still happily digs out and burns tons of coal (annoying our neighbors in the process). I hope you're proud of us.
It's not suboptimal, it's a geopolitical disaster that people in 50 years will look back on and ask "how did this happen?"
